1 Our invention relatesLto improvements vin llilling machines, and it consists in the conibinati'ons,constructions,A and arrangements herein described and claimed. 'p 'Anobject of ourinvention"y is "to provide alling'niachine which willf'fill bottles with charged liquids withouttheY loss' of gas7 or the production of foainin the bottles.

Al further object of our inventionis to provide a device ofthe type described which will provideva counter-pressure-in the bottle before the liquid valve is' opened, the' valve being'so constructed that when it is opened, the liquidwill flow down the' inside wall 'of l5 the 'bottle withoutdisturbingthe substance; such as syrup, nwhich happens lto'be within the bottle. Q Y

A further object of our invention' is to provide a device of the type described which chas means for adjusting-the- 'movement of ythe liquid valve externally. f y

A VurtherobjectlofVv our invention-is to providea device ofthe type described which has means forv receiving foam', thus `permit- ..25 ting the bottle'tov be lled'with the'natural Vliquid. when the devicer'isused for bottling heavily chargedlliquids 5" Y l A Vfurthenobjectl of our: invention is to provide a device of the type described which l30 will allow the pressurewithin thefbottl'e to release gradually, thus obviating the disturbance .of the'liqui'dgwhich would tend to produce foam" as this is a. general result. from releasing the pressurewinstantly.- v

Other objects and advantages Will appear in the following specificatiom and the novel features of the invention will be particularly pointed outin. the appended claims.Y Our invention -is illustrated in the accom-A forming part rof this ap-V lplcation,i11 Which l Y vFigure lA isa fr ntielevation of thedevice asappliedtoa Vliquid'ta'n'k, i
